SHOVEL-PLOW ATTACHMENT.

Specification of Letters Patent.

Patented Aug. 14, 1906.

Application filed November 27,1905. Serial No. 289,331.

To all whom it may concern:

Be it known that I, ROBERT L. BURNETT, a citizen of the United States ofAmerica, and a resident of Hatchers, county of Quitman, State ofGeorgia, have invented certain new and useful Improvements inShovel-Plow Attachments, of which the following is a full and clearspecification, reference being had to rub-iron and guide-bar; Fig. 6, asimilar view showing the opposite side of the iron; Fig. 7,?

a cross-section on the line 7 7 of Fig. 2.

The object of this invention is to provide a simple attachment forshovel-plows whereby the bar side of the plow-foot will be protectedfrom wear and the plow will be rendered more easy of guidance, as morefully hereinafter set forth.

Referring to the drawings by reference characters, the letter Adesignates the plowbeam; B and C, the two parallel bars of the plow footor standard, each of which is provided with an extension, (lettered,respectively, B and C,) which curves downwardly and rearwardly andupwardly and are each provided with a series of bolt-holes b throughwhich and the beam is passed a bolt b whereby the angle of the plow-footwith respect to the beam may be varied.

The plow-shovel D is provided with the usual removable point P, and onits rear side is formed a longitudinal rib d, which latter is adapted tobe clamped between the bars of the plow-foot by the two bolts 1 and 2.

The parts as above described are covered by my former patent, No.803,549, and I therefore make no claim to them in this application.

The combined rub-iron and guide is designated as a whole by the letterE, and it is bolted to the outer face of the left bar B of the plow-footby means of one of the bolts 2, that attach the shovel to the plow-foot.The body portion of the rub-iron is flanged around its forward and lowerand rear edges to form a socket e, in which fits the plow-foot bar, sothat when the device is bolted to the bar it is rigidly braced allaround. The letter 6 designates the hole through which the bolt 2passes. The front face of the rub-iron is beveled inwardly, so as to fltagainst the rear mclined face of the shovel, as shown most particularlyin Fig. 7. Thus 'beveling the inward face of the iron gives the frontflange e a wedge shape in cross-section, whereby when the iron is drawntightly to place by the bolt said flange e will be wedged between thefront edge of the bar B and the adjacent face of the shovel, thereby notonly bracing and supporting the shovel, but also fastening it moresecurely to the plow-foot,

preventing it becoming loose. Formed. integral with the upper rear edgeof the rubiron is a rearward-extending guide-bar e, whose lower edge isprovided with an inwardly-extending flange e.

In shovel-plows of this character the right-' hand bar of the plow-footis protected from wear by the shovel; but the left-hand or bar side ofthe plow-foot is not fully protected and is subjected to a great deal ofwear. My rubiron and guide protects this left bar from wear, since itcovers all that portion of the bar which is ordinarily subjected towear. It will be observed also that this attachment enables the plow tobe more easily guided, thereby making it easier to list or ridge up landwhen plowing down, as the furrows can be made closer together, therebybreaking the land more thoroughly. Furthermore, the guide prevents theplow from sheering off to the left, as all bar shovel-plows are in--clined to do, especially when throwing two furrows together. It will beobserved also that inasmuch as the guide works six or eight inches abovethe point of the plow it will be easier to break out middles than withthe ordinary plows provided with landsides even with or very near thepoint of the plow. It will be observed also that my device is extremelysimple and inexpensive to make, as the iron flts the plow-bar and cannot become loose or out ofline. It will be observed, further, that therub-iron protects the entire soil-engaging outer surface of the bar sideof the plow-foot and that this wearsurface is in the same plane with theedge of the bar side of the, shovel and with the upright guiding-surfaceof the guide-bar.

What I claim, and desire to secure by Letters Patent, is-

1. In combination with a plow-foot and a plow-shovel having a verticalflange which is embraced by the plow-foot, of a rub-iron covering andembracing the soil-engaging outer face of thebar side of the plow-footand pro-- IIO 'vided with a rearwardly-extending guidebar, said rub-ironbeing provided with a front flange which lies between the rear side ofthe shovel and the front edge of the adjacent part of the plow-foot,said flange terminating short of the plow-shovel flange.

2. In Combination with a shovel-plow, of an attachment consisting of abody portion adapted to be bolted to the bar side of the plow-foot andto embrace and cover the lower end thereof vand provided with a rear-Wardly-extending guide-bar, this guide-bar having a verticalguiding-faceand being connected, to the body portion, sothat while theplow is working this guide-bar- Will engage the soil near its surfaceonly, substantially as set forth. i

3. In combination, a plow-foot composed of separated bars, a plow-shovelhaving a flangev fitting between; said bars, a rub-iron embraoingwandcovering the soil-engaging .part of the bar-side of the plow foot andcarrying a rearwardly-extendlng guidebar, said rub-iron being providedwith a wedge-shaped flange e fitting between the. rear face of theshovel the front edge of the-plow-foot,

and a bolt 2 extending through the rub-iron and the plow-foot and theflange of the plowshovel. v a

4. In a shovel-plow the combination of a plow-foot and a plow-shovelattached there to, of a combined rub-iron and guide consisting of a bodyportion flanged to embrace the outer face of the bar side of theplowfoot and being of sufficient length to cover and protect theentiresoil-engaging. portion thereof and being provided with arearwardly-extending guide-bar, this guide-bar.

having an upright guiding-surface in. the same plane wlth the outersurface of the rub- .iron, the forward edge of the rubfiroin fittingagainst and supporting the plow-shovel, and

means for fastening the rub-iron to the plowfoot. I

In testimony whereof I hereunto affix my signature, in the presence of.two witnesses,
